The carbon footprint of training a single AI is 284 metric tonnes CO2e - or about five times the lifetime emissions of a car

(University of Alberta) New research provides insight into the structure of silicon nanocrystals, a substance that promises to provide efficient lithium ion batteries that power your phone to medical imaging on the nanos...

Scientists once thought that neurons, or possibly heart cells, were the oldest cells in the body. Now, researchers have discovered that the mouse brain, liver and pancreas contain populations of cells and proteins with e...

Research provides a possible new reason why human disease burden increases so sharply from the sixth decade of life onward as health-protective mechanisms disappear.

Researchers comparing American, Pacific and Southeast Asian subtypes of Zika virus have concluded that the American-subtype strain has the highest ability to grow both in vitro and in vivo.

Researchers have found mutations in 12 genes believed to be largely responsible for the onset of multiple sclerosis in families with multiple members diagnosed with the disease.

Researchers have discovered a potential drug compound that can block a mutagenic DNA repair pathway that helps cancer cells survive chemotherapy. When they treated mice with this compound along with cisplatin, a DNA-dama...

A new kind of CRISPR based on jumping genes could make it much easier to add pieces of DNA to genomes, leading to better treatments for many diseases

Scientists have recreated a critical brain component, the blood-brain barrier, that functioned as it would in the individual who provided the cells to make it. Their achievement provides a new way to make discoveries abo...

A new protein involved in Alzheimer's disease (AD) has been identified by researchers. CAPON may facilitate the connection between the two most well-known AD culprits, amyloid plaques and tau pathology, whose interaction...

Scientists have found that neural stem cells use molecules that form a complex called STRIPAK to 'wake up' and produce new neurons (nerve cells) and surrounding glial cells in the brain.

Researchers have discovered a new mechanism that brain cells use to protect themselves from protein aggregates. Such aggregates play a key role in Parkinson's and other neurodegenerative diseases.

In a study of 679 patients with 105 different rare diseases, scientists have shown that artificial intelligence can be used to diagnose rare diseases more efficiently and reliably. A neural network automatically combines...

Researchers report that they have developed a faster, easier and cheaper method for making new amino acid chains -- the polypeptide building blocks that are used in drug development and industry -- than was previously av...

New research uncovers leading mechanisms of separation of active from inactive fractions of the genome in the cell nucleus and turns our picture of the nucleus upside down.

A deep-sea survey has found more tiny particles of plastic far below the surface of the Pacific than floating on its surface, with the highest levels around 300 metres down

12 genes associated with familial multiple sclerosis have been identified. The findings provide a molecular rationale for the chronic inflammation, demyelination and neurodegeneration associated with MS. Identifying new ...

High-energy ion beams--laser-like beams of atomic particles fired through accelerators--have applications that range from inertial confinement fusion to the production of superhot extreme states of matter that are though...

A pair of 52 million-year old fossils discovered in Argentine Patagonia suggests that relatives of oak trees started life in the southern hemisphere, not the north

Using transcranial focused ultrasound in combination with injectable microbubbles, researchers open a pathway through the blood-brain barrier. The technique allows drugs to penetrate the brain and trigger therapeutic eff...

Neural small RNAs regulate germline genes to control behavior transgenerationally in nematodes.
